Definitions

  • a computer-assisted surgical system may include a robotic arm, controller, and navigational system.
  • Robotic or robot-assisted surgeries have many associated advantages, particularly in terms of precise placement of surgical tools and/or implants.
  • a trajectory is planned for a tool or series of tools attached to the robotic arm via a tool guide based on a surgical plan.
  • a first interaction with a patient is for a surgeon to create a skin incision at the intersection of the planned trajectory and the skin.
  • this is done with a simple stab incision through a scalpel guide placed in the tool guide.
  • the incision must be longer than a diameter of the tool guide, which is why the surgeon must manually enlarge the initial stab incision that was done through the scalpel guide which is disruptive of a flow of the surgical procedure.
  • the presently disclosed systems, devices, and methods improve computer-assisted surgical systems, for instance, by providing various embodiments of a scalpel guide.
  • the scalpel guide allows precise marking of the intersection of a planned trajectory for a surgical procedure and the skin with a stab incision with a scalpel using a first guide slot, and a guided single-plane incision that is longer than a diameter of the tool guide using a second guide slot that allows a swiveling motion of the scalpel along the single-plane.
  • the scalpel guide includes a handle and guide prongs that guide the scalpel depending upon a setting of the handle to permit a stab incision and a guided single-plane incision to be made on a patient as described below.
  • Some embodiments of the invention provide a surgical robot (and optionally a navigation system) that utilizes a positioning system that allows movement of a tool support to a planned trajectory where a longitudinal axis of the tool support is coaxially aligned with the planned trajectory.
  • the tool support has a first face, a second face, and an aperture from the first face to the second face.
  • the aperture may be coaxially aligned with the longitudinal axis and sized and shaped to receive a scalpel guide.
  • the scalpel guide has a body defining a first guide slot configured to receive a scalpel and guide a point of a blade of the scalpel to form a stab incision through a skin of a patient along the planned trajectory.
  • the body may also have a second guide slot.
  • the second guide slot may be sized and shaped to receive the scalpel and permit the scalpel to move laterally so as to permit the scalpel guided by the scalpel guide to move in an arc along a single plane thereby forming a single plane incision that is longer than a width of the second guide slot and/or an inside diameter of the tool support.
  • a scalpel guide having an elongated portion with a trajectory marker formed therein is described.
  • the trajectory marker indicates a planned trajectory.
  • the scalpel guide may also have a guide slot sized and shaped to allow a scalpel to be moved laterally only along an arc on a single-plane that intersects the planned trajectory.

Abstract

L'invention concerne des guides de scalpel destinés à être utilisés avec un guide d'outil d'un système chirurgical. Dans une version, le guide de scalpel comprend un corps délimitant une première fente de guidage dimensionnée et formée pour recevoir un corps d'un scalpel afin de guider une lame du scalpel le long d'un axe central sans aucun mouvement latéral du scalpel. Le corps délimite également une seconde fente de guidage agencée de telle sorte que le corps du scalpel introduit dans la seconde fente de guidage est guidé verticalement par les côtés de la seconde fente de guidage, et peut se déplacer horizontalement en travers du canal le long du plan de trajectoire. L'invention concerne également d'autres versions du guide de scalpel.
